Abstract: A driver assistance system is provided in a motor vehicle, which driver assistance system executes at least active transverse guidance interventions. The driver assistance system can be activated while decoupled from the activation of a longitudinal control system but can also be active both, with and without longitudinal control, and includes both a traffic jam assistance sub-function and a track guiding assistant sub-function.

The driver assistance system is characterized by a special combination of the sub-functions track guiding assistance and traffic jam assistance. They each take turns depending on the presence of conditions, which are defined differently for each sub-function.
